RevLefty,
I have a somewhat similar problem, but for a different reason. My UI has the pin over the fingers, cg out, no hole. The ball is shiny, not a mirror. I really have to be soft with my hand and keep my ball speed up, this ball has so much midlane. I can't get it to turn the corner properly from deep inside, it is really a heavy oil ball. My speed is slower than yours, and probably less revs.
I am thinking about drilling another with the pin about 5 1/2 inches from my axis, below left of my middle finger, cg out at about 45 degrees, and shiny. Small hole if needed. With your rev rate you could probably try this, and adjust surface as needed. With your small tilt, you might need to go over the fingers so that the track doesn't clip your fingers.
Ultimate Inferno is an awesome heavy oil ball, probably the best, but it is situational for alot of people. You might also try the new Impulse Zone. Looks REALLY good. Drilled one for a customer Saturday. Very strong ball, but different than the Warp Zone.
